Accuracy of the map:

Projection:

Basic contents:

The map is a vector file consisting of 1 basic and 2 subject layers. The species range is represented by polygons and dots.

Accuracy of the qualifier:

The dots represent information on the species localities: 1 - reliable data from herbarium and published sources; polygons (1) - generalized information on the species distribution from published sources and herbarium specimens.

Method of the map construction:

The data from the herbarium materials of LE, a published map of a part of the species range (Grossheim, 1952), and published data (Bobrov, 1945, 1987) were used for constructing the range of Trifolium angustifolium. The range consists of two polygons and dots. In Crimea, the species is distributed in the southern part (northward up to Simferopol), in the Caucasus it is distributed in Transcaucasia, Talysh and coastal areas of Daghestan. The southern border of the Caucasian polygon coincides with the state border of the former USSR.
